Pin an invisible sprite to the player where you want the camera to focus and scroll to that object.
If you want the player to be behind center pin it in front of the player. If you want the player to be lower on the screen pin the camera sprite above and in front of the player.

You can also use an image point instead of pin which would be easier if your player is moving backwards and forwards.
